Substance containment apparatus and method

ABSTRACT

A multi-chamber bottle includes an opening surrounded by a flange which has a spherical inner surface formed to receive a hollow member. The hollow member includes a lower opening and an upper opening. The housing is adjustable to bias the hollow member against the spherical inner surface of the flange, to seal around the opening. When closed, a portion of the hollow member blocks the opening. When open, the hollow member is in an upright position such that the opening of the bottle and the lower opening of the hollow member are aligned. A method for mixing two substances includes disposing an amount of one substance in the bottle, adjusting the hollow member to block the opening of the bottle, and disposing an amount of another substance in the hollow member. To mix the substances, the hollow member is rotated into the open position and the apparatus is shaken.

This application is a continuation-in-part of application Ser. No.07/804,883, filed Dec. 6, 1991, now abandoned.

BACKGROUND

1. Field of the Invention

The present invention relates to a multi-chamber substance containmentapparatus for separately storing two or more substances in onecontainer.

2. Description of the Prior Art

Dehydration is a common method of preserving perishable foods. Forexample, the usable periods ("shelf-life") of liquid milk is increasedfrom a few weeks to several months or more by dehydrating the liquidmilk to form powdered milk. Dehydrated substances are particularlyuseful when refrigeration is not available because the dehydratedsubstances can be stored at room temperature. Of course, when dehydratededible substances are re-hydrated by mixing with a liquid, theshelf-life of the re-hydrated edible substance is typically the same asor shorter than the perishable food from which the dehydrated substancewas produced. Therefore, it is advantageous to postpone the hydrationprocess until the dehydrated substance and liquid are mixed; that is,immediately prior to consumption.

FIG. 1 shows a prior art baby bottle 10 used to dispense liquid babyformula or milk. The baby bottle 10 includes an outer wall 11 defining achamber 12, a mouth 13 defining an opening 14, and a nipple assembly 15which covers the opening 14. The nipple assembly 15 includes a base 16and a nipple 17. The nipple assembly 15 is typically connected to thebottle portion 10 by means of mating threads 8 and 18 which are locatedon the mouth 13 and the base 16, respectively.

Powdered baby formula and water are mixed in the prior art baby bottle10 by inserting predetermined amounts of powdered formula and waterthrough the opening 14 into the chamber 12, attaching the nipple portion15, and shaking the baby bottle 10 until the powdered formula and watermix to produce liquid baby formula. The liquid baby formula is theneither immediately consumed or refrigerated for later consumption.

There are several disadvantages associated with the use of prior artsingle-chamber containers, such as the above-described baby bottle, forpreparing hydrated mixtures from a dehydrated substance. Onedisadvantage is that two storage containers are required to store thewater and the dehydrated substance prior to mixing. Mixing requirestransferring one of the dehydrated substance and the water from onecontainer to the other. The dehydrated substance and the water can becontaminated during the transfer, particularly when mixing is performedaway from home. In addition, in some situations, such as when mixing isperformed in a car, spillage or incorrect mixing quantities can resultbecause level surfaces and suitable measuring devices are not available.

Prior art containment apparatuses addressing the above-describeddisadvantages are taught in U.S. Pat. Nos. 2,793,776, 2,807,384 and2,813,649 (the "Lipari patents"). Each apparatus taught in the Liparipatents includes first and second chambers joined by a narrow channelwhich is blocked by an axially-displaced seal or a seal punctured by anaxially-displaced plunger.

A problem with the apparatuses taught in the Lipari patents is that thenarrow channel between the first and second chambers is too small toallow thorough mixing of the liquid and substance.

Another problem is that the axially-displayed seals and plunger impedemixing through the narrow channel after the seals are opened. That is,the liquid is impeded from entering the chamber containing the substancebecause the axially-displaced seals and plunger block a portion of theeffective "flow area" between the two chambers.

Another problem with the apparatuses taught in the Lipari patents isthat they are comprised of numerous parts and mechanisms. Therefore, theapparatuses are complicated to use and expensive to produce.

SUMMARY

The present invention is directed to an apparatus that satisfies theneed for a multi-chamber container which allows thorough mixing of twosubstances. The apparatus comprises a bottle having a first opening, anda hollow member which includes a curved wall and a second opening. Thehollow member is adjustable between a closed position, in which thecurved wall is disposed to block the first opening, and an open positionin which the first and second openings align to define a passage betweenan interior of the bottle and an interior of the hollow member.

The apparatus provides a sanitary method for storing and mixing twosubstances, such as water and powdered baby formula, which overcomes theproblems associated with prior art multi-chamber apparatus. The rotatingor pivoting action of the curved wall between the open and closedpositions provides a large, unobstructed flow area. In addition, therotating or pivoting action allows for a less complicated and lessexpensive design.

In a first embodiment the apparatus includes a bottle and a hollowmember, the hollow member being comprised of a housing connected to thebottle and a ball member rotatably disposed in the housing. The ballmember includes the second opening. A portion of the ball member blocksthe first opening of the bottle when the ball member is in a closedposition, and the second opening aligns with the first opening to form apassage between the interior of the bottle and an interior of the ballmember when the ball member is in an open position.

In a presently preferred embodiment, the hollow member is a spheredefining an upper opening and a lower opening, and the apparatus furthercomprises a housing adjustably connected to the bottle. The housingincludes an interior portion wherein the hollow member is rotatablydisposed when the housing is loosely connected to the bottle. When thehousing is tightly connected to the bottle, the hollow member is fixedlyheld in a selected position such as an open position, wherein the loweropening aligns with the first opening of the bottle, or a closedposition, wherein a portion of the hollow member blocks the firstopening of the bottle. The hollow member can be fixedly held such thatthe lower opening only partially aligns with the first opening in thebottle to provide a slower mixing of the substances stored in the hollowmember and the bottle.

In accordance with the present invention, a method of containing asubstance and a liquid for mixing at a predetermined time comprises thesteps of disposing a first predetermined amount of the liquid in abottle having a first opening, rotating a curved wall to block the firstopening, storing a second predetermined amount of a substance in ahollow member having a second opening, and at the predetermined time,rotating the curved wall away from the opening such that a passage iscreated between the liquid and the substance.

DESCRIPTION

As shown in FIGS. 2A to 2D, a substance containment apparatusincorporating the present invention includes a bottle 110 having a firstopening 115 and a hollow member 120 adjustably disposed adjacent thebottle 110. A connector 130 connects the hollow member 120 to the bottle110. The hollow member 120 includes a curved wall 121, a second opening125 and a third opening 126. A cover 105 is disposed over the thirdopening 126. The hollow member 120 is adjustable relative to the bottle110 such that when the hollow member 120 is in a closed (first)position, as shown in FIG. 2A, a portion 122 of the curved wall 121 isdisposed to block the first opening 115 of the bottle 110, and when thehollow member 120 is in an open (second) position, as shown in FIG. 2B,the first opening 115 and the second opening 125 align to define apassage (indicated by arrow P) between an interior 119 of the bottle 110and an interior 123 of the hollow member 120. The connector 130 fixedlyconnects the hollow member 120 to the bottle 110 in the open position,the closed position, or an intermediate position (not shown). The hollowmember 120 can be fixedly held such that the second opening 125 onlypartially aligns with the first opening 115 in the bottle to provide aslower mixing of the substances stored in the hollow member 120 and thebottle 115.

As shown in FIGS. 2A and 2B, in one embodiment of the present invention,the hollow member 120 is integrally formed with the curved wall 121. Inthis embodiment, the second opening 125 is formed in the curved wall121, and the curved wall 121 pivots or rotates relative to the bottle110 from the open position to the closed position. The curved wall 121can either be a planar curved surface, a spherical surface, or a surfacecombining planar and spherical portions. The remaining portions ofhollow member 120 can be any other shape, so long as adjustment from theopen position to the closed position is not impeded.

As shown in FIGS. 2C and 2D, in another embodiment of the presentinvention, hollow member 120' and curved wall 121' are formed asseparate elements. Hollow member 120' is a housing having second opening125' and third opening 126'. A removable cover 105' is disposed overthird opening 126'. Curved wall 121' is shown as a partial cylinder orsphere which is rotatably or pivotably disposed in the hollow member120'; however, the curved wall 121' can also be a full cylinder orsphere.

As shown in FIG. 2E, in another embodiment, bottle 110' includes anupper opening 116' covered by removable cover 105" and a lower opening115'. A hollow member 120" is adjustably disposed adjacent the loweropening 115'. In this embodiment the substances stored in the hollowmember 120" and in the bottle 110' can pass through the upper opening116' after the hollow member 120" is in the open position and the cover105" is removed.

A method of containing and mixing a substance and a liquid using thesubstance storage apparatuses described above includes the steps ofdisposing a first predetermined amount of the liquid in the bottle 110,adjusting the curved wall 121 to block the opening 115, and storing asecond predetermined amount of a substance in the hollow member 120. Ata desired mixing time, the hollow member 120 is adjusted such that thecurved wall 121 no longer blocks the opening 115, thereby allowing theliquid in the bottle 110 to mix with the substance stored in the hollowmember 120. The substance storage apparatus is then manually ormechanically shaken to thoroughly mix the substance and the liquid.

A benefit of the present invention over the containment systems of theprior art is that the curved wall 121 can be rotated away from theopening 115 of the bottle 110, thereby allowing a large, unobstructedpassage through which the substances stored in the bottle 110 and thehollow member 120 can be mixed. Further, the hollow member 120incorporating the present invention is inexpensive to manufacture, andsimple to use.

Other aspects and benefits of the present invention will become apparentin the following descriptions of two embodiments of the presentinvention.

First Embodiment

FIGS. 3 to 6B illustrate a first embodiment of a substance containmentapparatus incorporating the present invention.

As shown in FIGS. 3 and 4, the apparatus comprises a bottle 210 and ahollow member 220 comprised of a lower casing 230 connected to thebottle 210, an upper casing 240 disposed on the lower casing 230, means250 for connecting the lower casing 230 to the upper casing 240, and aball member 221 rotatably disposed within a hollow portion defined bythe upper casing 240 and the lower casing 230. A cover or nippleassembly 205 is optionally connected to the upper casing 240. All partsof the housing are preferably made of plastic and are produced usingknown molding methods.

As shown in FIG. 5, the lower casing 230 includes a lower portion 231,and an upper portion 232. The lower portion 231 includes a shelf 233which abuts a mouth of the bottle 210 when the lower casing 230 isconnected to bottle 210. The lower portion 231 includes an opening 234and includes lower threads 235. The lower threads 235 and the shelf 233are disposed to mate with the bottle 210 such that a passage is formedthrough the lower opening 234 and the opening 215 of the bottle 210. Theupper portion 232 includes upper threads 236 which connect the lowercasing 230 to the upper casing 240 using the connector 250, as describedbelow. The lower casing 230 also has a curved inner surface 237 shapedas a semi-sphere into which is formed a depression or seat 238. Thecurved inner surface 237 is formed to receive the ball member 221, andthe seat 238 is used as a pivot point about which the ball member 221 isrotated, as discussed below. Finally, an O-ring (not shown) isoptionally placed between the shelf 233 and the mouth of the bottle 210to prevent leakage.

The upper casing 240 includes a lower portion 241 which abuts the upperportion 232 of lower casing 230, and a neck 242 defining an opening 243.The lower portion 241 includes a shoulder 244 which is used to connectthe upper casing 240 to the lower casing 230 using the connector 250, asdescribed below. Threads 245 are disposed on the outer surface of theneck 242 such that a cover, such as a nipple assembly 205, can beconnected to the upper casing 240 to close the opening 243. The uppercasing 240 also has a spherical or curved inner surface 246 into whichis formed a cam groove 247. The curved inner surface 246 is formed toreceive the ball member 221, and the cam groove 246 is used to rotatethe ball member 221, as discussed below. Finally, an 0-ring (not shown)is optionally disposed between the upper portion 231 of lower casing 230and the lower portion 241 to prevent leakage.

The connector 250, shown as a locking ring in the present embodiment,includes a lip 251 and threads 252. The lip 251 rests on the shoulder244 of the upper casing and threads 252 engage the upper threads 236 oflower casing 230. When the connector 250 is rotated, the lip 251 pressesdown on the shoulder 244, thereby biasing the lower portion 241 againstthe upper portion 232 of the lower casing 230. Finally, connector 250 isnot limited to a locking ring and can be, for example, a fastener orclamp.

The ball member 221 is disposed in a hollow space defined by curvedinner surface 237 and curved inner surface 246. The ball member 221includes a spherical outer wall 222 which is sized such that when theupper casing 240 is biased toward the lower casing 230 by the connector250, the ball member 221 is fixedly held by opposing forced exerted fromthe upper casing 240 and lower casing 230. Note that when the ballmember 221 is fixedly held in this manner, the ball member 221 pressesagainst the upper casing 240 such that it cannot be rotated relative tothe lower casing 230. The ball member 221 defines a hollow interior 223and the outer wall 222 includes a blocking portion 224 and defines alower (second) opening 225. When the ball member 221 is in a closed(first) portion, the blocking portion 224 is disposed to block theopening 234 of the lower casing 230 and the opening of the bottle 210.Conversely, when the ball member 221 is in an open (second) rotatedposition, the lower opening 225 aligns with the opening 234 of lowercasing 230 and the opening of bottle 210 to form a passage from theinterior of the bottle 210 to the interior 223 of the hollow member 221.Further, a protuberance or pin 226 and a cam follower 227 are formed onthe outer wall 222. The pin 226 is pivotally disposed in the seat 238 ofthe lower casing 230. The pin 226 is used as a pivot around which theball member 221 is rotated between the open position and the closedposition. The cam follower 227 is slidably disposed in the cam groove247 of the upper casing 240. When the ball member 221 is rotated aroundthe pin 226, the cam follower 227 slides within the cam groove 247.Finally, the outer wall 222 defines first upper opening 228 and secondupper opening 229.

The above-described substance containment apparatus operates as follows.

The liquid and the substance are stored in the apparatus using thefollowing steps. First, a predetermined amount of liquid is stored inthe bottle 210 and the hollow member 220 is connected to the bottle.With the apparatus assembled as shown in FIG. 4, the connector 250 isthen loosened such that the upper casing 240 is pivotable relative tothe lower casing 230 and the ball member 221 is rotatable within theupper casing 240 and the lower casing 230. The upper casing 240 is thenpivoted around the axis X1 such that the cam follower 227 is forcedalong the cam groove 247 to rotate the ball member 221 around the axisX2 into the closed position shown in FIG. 6A. In the closed position,the blocking portion 224 is disposed over the opening 234 of the lowercasing 230 and the opening 215 of the bottle 210, thereby sealing theliquid from the interior 223 of the ball member 221. The connector 250is then tightened to fixedly retain the ball member 221 within the uppercasing 240 and lower casing 230 in the closed position. The cover ornipple assembly 205 is then removed from the upper casing 240, and apredetermined amount of a substance, such as powdered baby formula, isinserted through the first upper opening 228 into the interior 223 ofthe ball member 221. The cover or nipple assembly 205 is then connectedto the upper casing 240. In this state, the substance and liquid areboth stored separately within the apparatus, thereby allowing a longstorage period without refrigeration.

At a desired time, mixing of the liquid stored in the bottle 210 and thesubstance stored in the hollow member 220 is effected by adjusting thehollow member into the open position as follows. First, the connector250 is loosened to allow rotation of the upper casing 240 about the axisX1. The upper casing 240 is then rotated, thereby exerting a force onthe cam follower 227 such that the ball member 221 is rotated about theaxis X2 such that the blocking portion 224 is rotated away from theopening 234 of the lower casing 234 and the opening 215 of the bottle210. With the hollow member 220 in the open position the lower opening225, the opening 234 of lower casing 230, and the opening 215 of thebottle 210 align to form a passage between the interior of the bottleand the interior 223 of the hollow member, thereby exposing thesubstance to the liquid. With the ball member 221 in the open position,the connector 250 is retightened and the apparatus is shaken to mix thesubstance and liquid. The mixture can then be consumed through thenipple assembly 205.

The above-described operation steps can be altered without departingfrom the spirit or scope of the present invention. For example, thebottle 210 can be stored separately from the hollow member 220 until thedesired mixing time. However, this would require that a second cover beprovided to retain the liquid in the bottle, and there would be anincreased risk of contamination of the mixture because the liquid wouldbe exposed to the surrounding environment when the second cover isremoved to connect the bottle 210 to the hollow member 220.

Second (Preferred) Embodiment

FIGS. 7 to 9 illustrate a preferred embodiment of a substancecontainment apparatus incorporating the present invention. In thisembodiment, the apparatus comprises a bottle 310, a hollow member 320and a housing 330. All parts of the housing are preferably made ofplastic and are produced using known molding methods. In addition, thesizes of the parts are determined by the amount of the substances to bestored.

The bottle 310 includes a cylindrical body 311, a lip 312, threads 313formed above the lip 312, a neck 314 defining a (first) opening 315formed above the threads, and a flange 316 formed above the neck 314.For the production of eight ounces of hydrated mixture, the overalllength of the bottle 310 is between 4 and 6 inches, and the outerdiameter is between two and three inches. The neck 314 is preferablyformed such that the opening 315 is one inch or more in diameter. Theflange 316 has a spherical inner surface 317 which is formed as a socketto receive the hollow member 320. The flange 316 is preferably formed toextend a distance of between one-half and three-quarters of an inchabove the neck 314.

The hollow member 320 is formed as a hollow spherical body having acurved wall 321 defining a lower (second) opening 325 and a neck 326upon which are formed threads 327 and which defines an upper opening328. In an embodiment for producing eight ounces of hydrated mixture,the curved wall 321 is preferably between two and three inches in outerdiameter; the selected size being matched with the curved flange 316 ofthe bottle 310 such that the hollow member 320 is rotatable or pivotableon the curved inner surface 317. Both the upper opening 328 and thelower opening 325 communicate with an interior 329 of the hollow member320. The upper opening 328 is preferably one to one and one-half inchesin diameter to facilitate entry of a substance into the hollow member320. The lower opening 325 is preferably one inch or more to facilitatethorough mixing of the substance with the liquid stored in the bottle310.

The housing 330 includes a body 331 having a lower portion 332 and anupper portion 333. The lower portion is cylindrical and has an innerdiameter sized to fit over the threads 313 formed on the bottle 310.Threads 334 are formed on an inside surface 335 of the body 331 near anopen end of the lower portion 332. An upper opening 336 is formed at theupper portion 333 and is sized such that the neck 326 of the hollowmember 320 can pass through the upper opening 336 when the apparatus isassembled. Further, a shoulder 337 is formed on the upper portion 333which prevents the hollow member 320 from passing through the upperopening 336. A slot 338 is formed in the shoulder 337 in which the neck326 is disposed when the hollow member 320 rotates between the openposition and the closed position, as described below.

The above-described second embodiment of the substance containmentapparatus operates as follows.

The liquid and the substance are stored in the apparatus using thefollowing steps. First, a predetermined amount of liquid is stored inthe bottle 310 and the hollow member 320 is placed on the flange 316connected to the bottle, as described above. The housing 330 is thenplaced over the hollow member 320 such that the neck 326 extends throughthe upper opening 336. The threads 334 on the housing 330 are thenengaged with the threads 313 disposed on the bottle 310. The hollowmember 320 is then rotated in the housing 330 such that the neck 326slides in the slot 338 until the hollow member 320 is in a closedposition, as shown in FIG. 8. The housing 330 is then rotated relativeto the bottle 310 such that housing 330 is tightened to the bottle 310.As the housing 330 is tightened on the bottle 310, the shoulder 337pushes against the curved wall 321, thereby biasing the hollow member320 against the inner surface 317 of the flange 316. In the closedposition shown in FIG. 8, a portion of the curved wall 321 is disposedto block the opening 315 of the bottle 310 such that the liquid issealed in the bottle 310. A predetermined amount of a substance, such aspowdered baby formula, is then entered into the interior 329 of thehollow member 320 through the upper opening 328. A cover, such as nippleassembly 305, is then secured over upper opening 328, thereby sealingthe substance inside the hollow member 320. The apparatus is then storeduntil the desired mixing time.

At the desired time, mixing of the liquid stored in the bottle 310 andthe substance stored in the hollow member 320 is effected as follows.First, the housing 330 loosened on the bottle 310 such that the hollowmember 320 becomes rotatable within the housing 330. Note that thehousing is not removed from the bottle 310 during the loosening step,thereby preventing exposure of the substance and the liquid to thesurrounding environment. With the housing 330 in the loosened position,the hollow member 320 is rotated in the housing 330 such that the neck326 slides in the slot 338 until the hollow member 320 is in an open(upright) position, as shown in FIG. 8. In the open position, the loweropening 325 of the hollow member 320 is aligned with the opening 315 ofthe bottle 310, thereby forming a passage between the interior of thebottle 310 and the interior 329 of the hollow member 320. The housing330 is the retightened to the bottle 310 such that the flange 316 andthe curved wall 321 surrounding the lower opening 325 to form a sealaround the passage formed by the opening 315 and the lower opening 325.The apparatus is then manually shaken until the substance and the liquidare thoroughly mixed. The apparatus is then inclined such that themixture flows through the third opening 326. A nipple assembly (notshown) can be used to regulate the flow of the mixture through the thirdopening 326.

The plastic used to produce the hollow member 320 and the flange 316must be strong enough to withstand the biasing pressure when theapparatus is in the open or closed position. In addition, the preferredplastic is elastically deformable to produce a liquid-resistant sealaround the first opening 315, thereby preventing leakage when the hollowmember 320 is biased against the flange 316. Further, the preferredplastic is Food and Drug Administration approved for food storage,exhibits sufficient lubricity for smooth sliding without the need forlubricants, and is not structurally or chemically altered when subjectedto cleaning temperatures of up to 100° C. Several plastic materials arecurrently available which can be modified using known methods to meetthe preferred characteristics discussed above, such as polyethylene,polypropylene, and polycarbonate.

The substance containment apparatus embodying the present inventionovercomes the disadvantages of the prior art by providing a sanitarymethod for separately storing two substances, such as water and powderedbaby formula, which have a short shelf-life once mixed, until a desiredmixing time. In addition, the present substance containment apparatusovercomes the disadvantages of the prior art two-chamber apparatus inthat a large, unobstructed flow area is provided, thereby allowingcomplete mixing of the two substances.

Although the present invention has been described in considerable detailwith reference to certain embodiments thereof, other containersembodying the present invention are possible. For example, the ballmember 221 of the first embodiment can be truncated to include only theblocking portion 222. In addition, applications of the apparatus andmethod incorporating the present invention are not limited to ediblesubstances; the apparatus can be used for storing numerous reactivesubstances whose mixture is beneficially contained within a singlecontainer. Further, the apparatus can be made from metal, ceramic or anyother material, so long as seals, such as rubber O-rings, are providedto prevent leakage.
